Abstract
This study investigates the microstructure and mechanical properties of aluminum-steel explosive clad produced in both open-air and underwater environments. The clads obtained in open air exhibited porous, molten zones, while those obtained underwater displayed uniform and refined microstructures due to rapid quenching. Numerical simulations using the smoothed particle hydrodynamics (SPH) method in ANSYS AUTODYN revealed elevated temperature and pressure during the process. Although both conditions resulted in clads with increased interface hardness, the underwater clads demonstrated an 18% higher ram tensile strength. Additionally, an analytical welding window was developed, validating the optimal conditions for successful cladding.
